RESUMO

BACKGROUND: Hospitalizations for ambulatory care sensitive conditions (ACSC) incur substantial costs on the health system that could be partially avoided with adequate outpatient care. Complications of chronic diseases, such as diabetes mellitus (DM), are considered ACSC. Previous studies have shown that hospitalizations due to diabetes have a significant financial burden. In Mexico, DM is a major health concern and a leading cause of death, but there is limited evidence available. This study aimed to estimate the direct costs of hospitalizations by DM-related ACSC in the Mexican public health system. METHODS: We selected three hospitals from each of Mexico's main public institutions: the Mexican Social Security Institute (IMSS), the Ministry of Health (MoH), and the Institute of Social Security and Services for State Workers (ISSSTE). We employed a bottom-up microcosting approach from the healthcare provider perspective to estimate the total direct costs of hospitalizations for DM-related ACSC. Input data regarding length of stay (LoS), consultations, medications, colloid/crystalloid solutions, procedures, and laboratory/medical imaging studies were obtained from clinical records of a random sample of 532 hospitalizations out of a total of 1,803 DM-related ACSC (ICD-10 codes) discharges during 2016. RESULTS: The average cost per DM-related ACSC hospitalization varies among institutions, ranging from $1,427 in the MoH to $1,677 in the IMSS and $1,754 in the ISSSTE. The three institutions' largest expenses are LoS and procedures. Peripheral circulatory and renal complications were the major drivers of hospitalization costs for patients with DM-related ACSC. Direct costs due to hospitalizations for DM-related ACSC in these three institutions represent 1% of the gross domestic product (GDP) dedicated to health and social services and 2% of total hospital care expenses. CONCLUSIONS: The direct costs of hospitalizations for DM-related ACSC vary considerably across institutions. Disparities in such costs for the same ACSC among different institutions suggest potential disparities in care quality across primary and hospital settings (processes and resource utilization), which should be further investigated to ensure optimal supply utilization. Prioritizing preventive measures for peripheral circulatory and renal complications in DM patients could be highly beneficial.

RESUMO

Bacterial meningitis is one of the diseases that, despite the introduction of several vaccines, remains a serious public health concern. Streptococcus pneumoniae (Spn), Neisseria meningitidis (Nm), and Haemophilus influenzae (Hi) are responsible for most cases diagnosed in children, adolescents, and adult population. Rapid, sensitive, and specific laboratory assays are critical for effective diagnosis and treatment, particularly in countries like Mexico in which culture positivity rates are very low due to the use of antibiotics prior to sample collection and to delay in transporting samples to the laboratory. The aim of this study was to evaluate the use of real-time polymerase chain reaction (RT-PCR) of cerebrospinal fluid (CSF) as a rapid diagnostic test for bacterial meningitis and compare these results with bacterial culture in three general hospitals in Mexico. During a 5-year period (2014-2018), a total of 512 CSF samples obtained from patients in whom infectious meningitis was suspected as initial clinical diagnosis were tested with RT-PCR with species-specific targets for the three pathogens. For Spn, 5.07% samples were RT-PCR positive; 0.39% for Nm and none for Hi. Only five RT-PCR Spn positive samples had a positive culture. Sensitivity and specificity estimates for RT-PCR are 100% and 95.46%, respectively. DNA amplification methods can provide better sensitive diagnostic tests than the reference standard, which is culture, particularly when antimicrobial treatment is initiated before clinical samples can be obtained.

Abstract: Objective: To compare the quality of care for neonates with neonatal sepsis, intrauterine hypoxia, prematurity and perinatal asphyxia in accredited hospitals (HA) and unaccredited (HNA). Materials and methods: 28 hospitals of the Ministry of Health were evaluated in 11 states in Mexico; the evaluation included infrastructure, equipment and supplies, quality management processes, and clinical quality indicators. LQAS was used, and average fulfillment of criteria and indicators in AH and NAH was estimated. Results: There were significant differences in favor of HA in equipment and supplies and, not significant, in the existence and functioning of hospital committees. There were no consistent or significant differences in compliance with clinical indicators between the AH y NAH. Conclusions: Accreditation for the care of newborns with the selected diagnoses is not associated with differences in the quality of care.

RESUMO

OBJECTIVE: To identify and quantify potentially inappropriate prescribing (prescripción potencialmente inapropiada, PPI) and other drug prescribing problems in public health care services in a population-based study at the three existing levels of complexity in Mexico. METHODS: Descriptive analysis of the Study on Satisfaction of Users of the Social Protection System in Health 2014-2016, prescription and drug supply section, to obtain the prevalence of PPI in older adults (≥ 65 years), based on Beers, STOPP, Prescrire and BSP listings using AM (older adults) prescription indicators, one for each listing. RESULTS: Most older adults (67%) were prescribed at least one medication, with a mean of 2.7 medications per prescription. The PPI prevalence was 74% according to the BSP criteria, 67% according to the STOPP listing, 59% with the Beer criteria, and 20% with Prescrire. The most frequent PPI prescriptions were NSAIDs, vasodilators and sulfonylureas. CONCLUSIONS: The use of PPIs in AM is high in Mexico. The higher prevalence found in this study may reflect the use of a source with population representativeness. The partial use and adaptations of the criteria make difficult comparing the studies; however, the STOPP criteria are the ones with the highest prevalence, as they cover a greater number of drugs and their use is more common in the first level of care.

RESUMO

Introduction: Urethral and bladder neck stricture (U/BNS) is a complication that occurs in up to 9% of patients following transurethral resection of the prostate (TURP). The most relevant risk factors reported are prolonged surgical duration and prostatic volume. The purpose of this study is to analyze risk factors associated with the development of U/BNS following TURP. Materials and Methods: Case-control study. Population: patients who underwent TURP. Cases: patients with U/BNS following TURP, diagnosed between January 2010 and December 2018. We included patients with obstructive symptoms after TURP with clinical or radiographical evidence of U/BNS. Controls were patients who underwent TURP between January 2016 and December 2017, without evidence of stricture. Patients with history of pelvic fracture and previous U/BNS were excluded. We analyzed as risk factors age, prostatic volume, diabetes mellitus, previous use of transurethral catheter, urinary tract infection, bladder calculi, prostate cancer, previous TURP, resection time, resected volume during TURP, transoperative complications, and number of surgical procedures performed during the same event. We used chi-square or Mann-Whitney's U test for between-group comparison; association was established by odds ratios (ORs) and 95% confidence interval (CI), variables with p < 0.05 were included in the logistic regression. Results: We included 101 cases and 207 controls. Cases had lower incidence of prostate cancer, smaller prostates, less resection time during TURP, lower grams resected and prostate-specific antigen values than controls. History of transurethral catheter was more frequent in controls than cases (46% vs 29%, p = 0.004); there were no differences between groups in the other factors analyzed. On multivariate analysis, the use of a transurethral catheter was a protective factor against U/BNS (OR 0.16, 95% CI 0.064-0.442, p < 0.001). Conclusions: In this study, the use of urethral catheter before TURP is a protective factor against U/BNS.

RESUMEN OBJETIVO Identificar y cuantificar la prescripción potencialmente inapropiada (PPI) y otros problemas en la prescripción de medicamentos en los servicios públicos de atención médica en un estudio poblacional en los tres niveles de complejidad existentes en México. MÉTODOS Análisis descriptivo del Estudio de Satisfacción de Usuarios del Sistema de Protección Social en Salud 2014-2016, sección de prescripción y surtimiento de medicamentos, para obtener la prevalencia de PPI en adultos mayores (≥ 65 años) con base en listados Beers, STOPP, Prescrire y BSP mediante indicadores de prescripción en AM, uno por cada listado. RESULTADOS Al 67% de los AM se les prescribió al menos un medicamento, con una media de 2.7 medicamentos por receta. La prevalencia de PPI fue del 74% según los criterios BSP, del 67% según el listado STOPP, del 59% con los criterios Beer y del 20% con Prescrire. Las prescripciones PPI más frecuentes fueron los AINES, vasodilatadores y las sulfonilureas. CONCLUSIONES El uso de PPI en AM es alto en México. La mayor prevalencia encontrada en este estudio puede ser reflejo de la utilización de una fuente con representatividad poblacional. La utilización parcial y adaptaciones de los criterios dificultan la comparabilidad entre estudios, sin embargo, los criterios STOPP son los que más altas prevalencias han presentado debido a que abarca un mayor número de medicamentos y su uso más habitual en el primer nivel de atención.

RESUMO

UNLABELLED: There are few reports on the impact of diabetes in the geriatric population. OBJECTIVE: To determine the prevalence of diabetes in the geriatric population in a hospital in Northeast Mexico. DESIGN: A cross-sectional study and a probabilistic sampling were made. The files of outpatients of the geriatrics department in a General Hospital in Monterrey, Mexico,were examined. The information obtained from these files was related to the patient's personal pathological and non-pathological background, besides a full geriatric evaluation. RESULTS: A total of 171 files were examined, out of which 97 (56.7%) belonged to females and 74 (43.3%) to males. The mean age was 78 ± 6.9 years. Diabetes was found in 76 patients (44%), major depression was found in 85 patients (50%), with the latter being more common in diabetic patients (p = 0.002). It was also found that diabetic patients take more drugs during their disease. Adjusting for age, gender, and academic level, cognitive impairment was found in 110 patients (64.3%). CONCLUSIONS: Diabetes mellitus is more frequent in the geriatric population and it uses more resources.

RESUMO

OBJECTIVE: To evaluate level of development that medical interns achieve, before graduating, in critical reading ability during their internship in five general hospitals. MATERIAL AND METHODS: During the academic year, we compared the initial and final scores of critical reading of medical interns before graduation in five general hospitals in IMSS. An instrument using 98 items that explored interpretation, judgment and proposal was developed and validated by four medical education researchers. In hospitals 1, 4, and 5, professors developed active-participative strategies related to critical reading in clinical research. In Hospital 2, no course was given and in Hospital 3, a traditional course (mainly clinical exposure) was offered. RESULTS: The final global scores were better for those students in Hospitals 1, 4 and 5 versus Hospitals 2 and 3 (median: 31, 29, 31 versus 9 and 24) (Kruskal-Wallis < 0.05). Initial and final differences in global and interpretation, judgment and proposal were also better in those same students. CONCLUSIONS: Active-participative educational strategies may develop the ability for critical reading of clinical research in internship and these strategies must be included in the curriculum during internship.

RESUMO

Background: Indoor pollution can be an important risk factor for human health, considering that people spend more than 60 percent of their time in their houses. Aim: To investigate indoor pollution in a zone of extreme poverty in Metropolitan Santiago. Material and methods: During 24h, carbon monoxide (CO), sulfur dioxide (SO2), respirable particulate matter (PM10), polycyclic aromatic hydrocarbons absorbed in PM5, temperature and humidity, were measured in the interior of 24 houses in La Pintana, Santiago. Results: The higher pollutant concentrations were observed during hours when heating was used, in houses that used coal (mean PM10 250 µg/m3, CO 42 ppm, SO2 192 ppb) or firewood (mean PM10 489 µg/m3, CO 57 ppm, SO2 295 ppb). In all houses, polycyclic aromatic hydrocarbons were detected and they came from the interior of the house and not from external filtered air. Coal, firewood and cigarette smoke were important sources of carcinogenic and kerosene and gas were sources of non carcinogenic polycyclic aromatic hydrocarbons. Conclusions: In the houses studied, the population was exposed to an accumulation of highly toxic pollutants, caused by a lack of ventilation. A high relative humidity also contributed to the growth of biological pollutants

RESUMO

Three hundred and nine consecutive arterial blood samples received at the central laboratory of a public hospital were analyzed. Patient data in the order form, reception conditions at the laboratory, transport media, time of arrival and analysis of each sample were recorded. Five percent of orders informed the hour of sampling 0.6 percent the patient's temperature and 18.1 percent the inspirated oxygen fraction. Bubbles or clots were present in 12.9 percent and 3.2 percent of samples respectively; 87.3 percent of samples were well sealed and the amount of blood withdrawn in relation to the syringe capacity was optimal in 47.2 percent of cases. Ninety three percent of syringes were transported with ice cubes that did no cover the syringe and 5.8 percent of samples were received at room temperature. The delay in analysis, since the time of reception at the laboratory, ranged from 0 to 55 min (mean 12.9 min). Several deficiencies in pre analytical variables in blood gas analysis were identified, most caused by neglect and susceptible of correction. Quality controls for this determination should be performed frequently
